STEA -TRAP.

Specification of Letters Patent.

Application filed March 31, 1913. Serial No. 757,745

To all whom it mag concern I Be it known that I, ARTHUR BOOZER, of thecity and county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in Steam Traps; and I do'herebydeclare the following specification, taken in connection with theaccompanying drawings, forming a part of the same, to be a full, clear,and exact description thereof.

The invention relates to steam traps and has for its object to simplifyand improve the construction whereby the efficiency of the operationwill be greatly increased.

To these ends the invention consists in the novel arrangement andcombination of parts hereinafter described and more particularly setforth in the claims. 1

In describing the invention in detail reference will be made to theaccompanying drawings, in which' Figure 1 is a central longitudinalsectional elevation of my novel form of steam trap, the valve operatingmechanism being shown in full lines in the position which it occupieswhen the valve is closed and in dotted lines when the valve is open.Fig. 2 is aplan view in section on line 00-02, Fig. 1. Fig. 3 is atransverse section on an enlarged scale on line 3 1 Fig. 1.

Referring to the drawings, 1 represents an egg-shaped shell or casingwhich is provided upon the side adjacent'the bottom with a horizontallyextending neck portion 1 and upon the opposite side adjacent the topwith an inlet-pipe 2 through which the steam or water of condensationmay enter the trap. The neck portion 1' is provided with a cover-plate 3which is bolted to the.

casing aiid is provided with a screw-threaded opening 4 extendingthrough the same. Mounted in the outer end of the opening '4 is anoutlet-pipe 5 and screwed into the inner end of said opening is arectangular hollow frame or support 6 having end walls .7 and 8, apartition wall 9 arranged between and parallel with said end walls andan externally threaded neck portion 10 formed integral with the end wall8. The partition wall 9 divides the frame 6 into two compartments 11 and12. The compartment 11 is open at the top and bottom and provided with alongitudinal slot 13 in each side, and the compartment 12 is closed atthe top and bottom and provided with an opening 14 in each side.

Removably mounted in the neck portion 10 and extending through the sameis a 'hollow conical valve-seat '15, and mounted to slide'in the walls 7and 9 is a valve-stem 16 provided at each end with a conical valve 17Said valve-stem 16 is also provided with a pin 18 extending radiallythrough the central portion of the same and having the ends projectthrough the slots 13 in the sides of the frame 6. Said pin 18 has aloose fit in the valve-stem 16 and is provided at each'end with athumb-nut 19 for holding the same in position.

A pair of parallel arms 20 are pivoted at their lower ends upon a pin 21secured in ears 22 upon the bottom of the frame 6 and have their upperendsjoined together by a pin 23. Said arms 20 are each provided with alongitudinalslot 24 through which the pin 18 extends. A float-lever 25is provided at its free end with a hollow float 26 Patentedflct. 3,1916. I

and is pivoted at the opposite end upon a pin 27 secured in ears28 uponthe top of the frame 6, said pin 27 being arranged in vertical alinementand parallel with the pin 21. Said float-lever 25 is provided at its:pivoted end with a downwardlyextending lateral projection 29 which isprovided" The parts are normally in the position shown in full lines inFig. 1, with the valve 17 in closed position. As the water ofcondensation begins to rise in the casing 1 the float 26 likewise risesand. moves the float-lever 25 upon its pivot, thereby moving theprojection 29 and the upper ends of the arms 20 to the left in Fig. 1.As the arms 20 are rocked to the left the pin 18 which engages the slots24 will likewise be moved to the left in slots 13, thereby moving thevalve-stem 16 to the left and opening the valve 17 When the water ofcondensation has passed out through the outlet-pipe 5 the float 26 willfall, thereby moving the projection 29, arms 20, and valve-stem 16 tothe right and clos-' ing the valve 17 WVith the above construction itwill be seen that the means for moving the valvestem engage said stem atits center and between its two supporting walls, and there is lessliability of any cramping or bending of said valve-stem or unevenwearing of its bearings. It will likewise be seen that by re movingone'of the nuts 19 the pin 18 can be removed and the valve-stem 16reversed so as to bring the other valve 17 in operative position withthe valve-seat 15. It will also be seen that by locating the neckportion of the casing above the bottom of said casing and by closing thebottom and top of the compartment 12 there is less liability of anysediment entering said compartment and collecting upon the valve orvalve-seat.

l Vhat I claim as my invention and de sire to secure by Letters Patentis:

slot, a float connected to said float-lever, and an arm pivoted at oneend to a fixed support and provided at its opposite end with means forengaging said slot, said outlet-valve be ing provided with a pin inpivotal engagement with said arm intermediate its ends.

2. An article of the character described comprising a suitable casinghaving an inlet and outlet, an outlet valve seat, an outlet valve havinga stem slidably mounted, a pivoted float lever provided with a slot, afloat connected to said float lever, and an arm pivoted at one end to afixed support and provided at its opposite end with means for engagingsaid slot, said outlet-valve stem being provided midway its length witha pin in pivotal engagement with said arm intermediate its ends.

3. An article of the character described comprising a suitable casinghaving an inlet and outlet, an outlet valve seat, an outlet valve havinga stem, a support for said valve stem, a float-lever pivotally mountedon said support and provided with a slot, two parallel arms pivoted atone end to a fixed support and joined together at the opposite end by apin arranged to engage said slot, a longitudinal slot in each armbetween the ends thereof, and a pin loosely mounted in the center ofsaid valve-stem arranged to engage said longitudinal slots.

4. An article of the character described comprising a suitable casinghaving an inlet Copies of this patent may be obtained for five centseach. by addressing "Washington, D. C.
